The inevitability of friction is one part of the human condition, and the drive to eliminate it is another. What separates humans from animals is that we can evolve intellectually by amassing tools and knowledge over generations about what causes friction and what we can do to eliminate it. But eliminating friction just means we get to work on harder problems, like how to leave this planet. So you never truly eliminate it, you just change its nature.

Btw, a bidet is pretty good.
